See how much of your monthly payment may end up going toward the principal, and how much may end up as an interest payment over the life of the loan. Not all monthly mortgage payments are the same.

Amortization Calculator Help

Amortization is the repayment of a mortgage loan through monthly installments of principal and interest for a duration of a set time period, usually a 30-year term. Use this calculator to understand your home repayment process. You can also use this calculator before you purchase a home to discover which payment term works better for your financial goals.

To use the calculator, enter the following information:

Loan Amount

Enter the amount of your home loan, not the purchase price of your house. You do not want to include your down payment in this section.

Loan Term

Choose from 15-year fixed, 30-year fixed, and 5/1 ARM. Your loan term will affect how much you pay in interest for the life of the loan.

Interest Rate

Fill in your exact interest rate for accurate calculations. Even a fraction of a percent will make a difference in how much you pay. If you haven’t purchased a home yet, keep the pre-filled rate in this box.

Advanced Report

This will show you how much of each monthly payment goes to interest and principal. The report will also show you the remainder of the loan for each year.
